Title: Protective circuit for recording head
Inventor: NAGATOMO AKIRA
IPC: B41J29/38
Filed: 1985-05-15
Abstract: PURPOSE:To prevent the thermal breakage of a recording head from occurring, by providing the first circuit for inhibiting energization when the energizing time for a recording head reaches a prescribed time, and the second circuit for inhibiting energization when the frequency of energization of the head reaches a prescribed value. CONSTITUTION:When the printing head is continuously energized for a period of time in excess of a prescribed energizing time, a printing time counter 1 stops outputting of a printing energization enable signal S3, and simultaneously outputs a prescribed energizing time exceeded signal S4. The signal S4 causes a controlling circuit 7 to actuate a circuit breaker 6 to break the circuit, whereby inputting of a counter clock S2 to the counter 1 is stopped. When the frequency of energization for the printing head exceeds a prescribed value, a rest time for the head is calculated by a duty-setting circuit 2 on the basis of a count in the counter 1 obtained according to the supplying time of an in-printing signal S1, the value stored in a printing rest time register counter 3 is compared with the count in a non-printing time counter 4 by a comparator 5, and if necessary, the energization for the head is stopped.

Title: Nonlinear discharge lamp
Inventor: HAGIWARA MAKI
IPC: H01J61/44
Filed: 1982-06-16
Abstract: PURPOSE:To provide a nonlinear discharge lamp made of soda glass with an extremely small deterioration rate of luminous flux due to coloring, by applying the phosphor material whose specific surface area being 2,500cm<2>/g to 5,000cm<2>/g to the inner surface of the soda glass tube. CONSTITUTION:As the inorganic compound to be applied, oxide of alkaline earth metal such as pyrophosphate, orthophosphate, or halophosphate, or alumina, silica, titanium oxide, or the like is preferred. As for the applied amount, it is desired that the specific surface area of the phosphor material after the application will be 2,500 to 5,000cm<2>/g. While the specific surface area of a normal phosphor material is 2,000 to 3,000cm<2>/g, the phosphor material whose specific surface area is below 2,500cm<2>/g is less effective in preventing the deterioration of luminous flux due to coloring by mercury; in this case, the applied amount of the phosphor coating must be 7mg/cm<2> or more. With the phosphor material of 2,500cm<2>/g or more, the coloring is effectively prevented by application of the phosphor material of 5mg/cm<2> or more.

Abstract: PURPOSE: To close fuel supply valve and cut off the electric supply to the control circuit during an abnormal time by connecting in parallel one of the points of relay which actuates a fan and one of the contact points of relay which works by flame detection, to an ignition switch.  
     CONSTITUTION: During an abnormal time such as accidental fire, etc., a flame detection circuit 42 drives a relay 43 to be turned off, causing the contact points 29, 41 to be in "OFF" position. Later the switches 39, 53 are turned off. The turning off of switch 39 causes relay 38 to be in "OFF" position and in turn, its contact points 6, 41 to be disconnected. As a result, fuel supply valve 8 is closed. Simultaneously, contact point 41 is turned off, cutting off the electric supply to proportional control circuit 61 and turning off switch 32 which is driven at a signal transmitted by the proportional control circuit 61. The turning off of switch 32 causes the relay 31 to be in "OFF" position, causing it contact points 10, 29 to be disconnected. The disconnection of the contact point 29 results in the shut-off of the electric supply to the control circuit.

Abstract: PURPOSE: To provide a method for effective plasma cleaning of the interior of a physical vapor deposition chamber for which a collimator is used between a target and a substrate support.  
     CONSTITUTION: When the collimator 34 is used between the target and substrate support 16 within the physical vapor deposition chamber 14, the collimator 34 is grounded to the wall surface of the chamber 14 and, therefore, the collimator 34 functions as a barrier of the plasma and the chamber 14 is electrically divided. Then, there is a need for executing two steps of plasma cleaning treatments in order to remove the natural oxide or the like from the component elements of the chamber 14 at the time of exchanging or removing the component elements of the chamber in particular. In the cleaning step of the first plasma, the upper portion of the chamber including the front surface of the collimator 34 is cleaned similarly with a conventional process. A positive bias power source is then connected to the substrate support 26 and the second plasma for cleaning is generated between the collimator 34 and the substrate support 1, by which the lower portion of the chamber including the rear surface of the collimator 34 is cleaned.

Abstract: PURPOSE:To realize manufacturing an outer semiconductive layer being excellent in mechanical strength, high-temperature materiality, high-temperature cross- linking properties and peelability by compounding a specified oil furnace black with a specified ethylenevinyl acetate copolymer resin to form the layer. CONSTITUTION:The outer semiconductive layer 5 of a cross-linked polyethylene- insulated cable 1 is formed through the process of compounding 40 to 80 pts.wt. of an oil furnace black having its average particle diameter of 30 to 52 millimicrons and its specific area of less than 100 square meters per gram with 100 pts.wt. of an ethylene-vinyl acetate copolymer resin containing 30 to 40wt% of vinyl acetate. The peeling strength of less than 4kg/12.7mm can thus be obtained also with the improvement of mechanical strength so as to peel the layer off the cable without causing its one-sided extension even under the high temperature of an extent of 50 degrees centigrade, for instance, and to further prevent any lowering of its softening temperature so that a cross-linking temperature required for the high temperature dry-type cross-link process of forming the layer can be heightened without causing any increase in the quantity of acetic acid being deacetified, resulting from its high-temperature decomposition.
